Title: Leakage sensitive x-ray radiographic flaw detector
Inventor: HIRAMA YUTAKA
IPC: G01N23/18
Filed: 1995-10-12
Abstract: PROBLEM TO BE SOLVED: To inform a situation of something wrong at a real time by installing a sensing means, sensing a leakage of X-rays, in an X-ray radiographic flaw detector. SOLUTION: A handrail 1 during man-conveyor driving is inserted into an X-ray radio-graphic flaw detector 9 provided with a leakage sensitive sensor 10, pushing a power switch 9D. Subsequently, an X-ray generating switch 9C is pushed, thereby generating X-rays from an X-ray generating part 9A. The presence of any damage to a reinforcing wire in an inner part of the handrail 1 is judged by a rupture pattern 1AX displayed on a display film of an X-ray display part 9B. At that time, in the case where something wrong such as leakage or the like has occurred in the X-ray radiographic flaw detector 9, it is sensed at once by the leakage sensitive sensor 10, and if it exceeds the safety setting value, this abnormal state is informed to an operator by a buzzer 9E or a warning lamp 9G.  In addition, even in the case where the operator becomes unaware of information on the trouble happening as well as if it has exceeded the setting value of X-rays the X-ray generating switch 9C is automatically interrupted. Therefore, any possible exposure and leakage accidents against the operator are thus prevented.

Title: Electrostatic recording apparatus
Inventor: NAKAYAMA KENJI
IPC: B41J2/385
Filed: 1990-10-02
Abstract: PURPOSE:To stably form a sharp recording image having high resolving power by forming at least the part holding a recording electrode of a developer carrier member from an insulating material and forming a large number of recessed parts to the surface of the insulating material part and respectively arranging recording electrodes to the bottom surfaces of the recessed parts. CONSTITUTION:Recording electrodes EL are arranged to a large number of the grooves G parallelly formed to the surface of an insulating coating layer 17c becoming a developer carrying surface so as to extend in a developer feed direction so that the leading end parts of the recording electrode wires 17a thereof extend on the bottom surfaces of the grooves G. The magnetic toner (d) fed to the surface of the insulating coating layer 17c enters the grooves G at a recording position W. Since the magnetic permeability of the magnetic toner (d) is larger than that of the insulating coating layer 17c forming both side walls of the grooves G, the line of magnetic force generated from a magnet roll is converged to the grooves G. The magnetic toner (d) runs in a line along the converged line of magnetic force to gather on each of the recording electrodes EL and a toner chain extending toward a cylindrical electrode 5 is formed. Since no magnetic toner (d) is almost present between the adjacent recording electrodes EL, EL, the generation of a voltage leak phenomenon between the recording electrodes EL is certainly prevented and a sharp toner recording image can be formed.

Title: Saw blade centering method in band saw machine and its device
Inventor: UEHARA MINORU
IPC: B23D53/04
Filed: 1996-10-07
Abstract: PROBLEM TO BE SOLVED: To easily adjust the inclination of a following wheel by directly tilting a wheel shaft. SOLUTION: A band saw blade is wound on a driving wheel and a following wheel 2, which is borne on the one end side of a wheel shaft 43, and the other end side of the wheel shaft 43 is fluctuatably detachably supported on a movable shaft support body 47. When the shaft support body 47 is moved in the longitudinal direction of the band saw blade, tension acts on the band saw blade to tilt the wheel shaft 43 for causing a center slippage in the following wheel 25. Since a longitudinal part of the wheel shaft 43 is partially detachably supported on the shaft support body, the end part of the wheel shaft 43 becomes fluctuatable, and the inclination of the wheel shaft 43 can be directly adjusted by movedly adjusting the end part of the wheel shaft 43 in the longitudinal direction of the band saw blade, and the inclination of the following wheel 25 can be therefore easily adjusted.

Filed: 1990-10-05
Abstract: PURPOSE:To insert packaging tapes into space and bind accumulated workpieces without additional time and labor by accumulating workpieces on a accumulation table with the space having width of the partition plate provided in an abutting state on the fixed stopper of a accumulation truck while butting the workpieces to the partition plate. CONSTITUTION:Workpieces W machined in a plate shape are accumulated in multiline by a fixed number due to the vertical and horizontal motion of a lifter 109 on a pallet P placed on the rollers 127 of an accumulation table 125.
